Send custom headers with UIWebView loadRequest
- by Thomas Clayson
I want to be able to send some extra headers with my UIWebView loadRequest method.
I have tried:
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://www.reliply.org/tools/requestheaders.php"]];
[req addValue:@"hello" forHTTPHeaderField:@"aHeader"];
[self.theWebView loadRequest:req];
I have also tried subclassing the UIWebView and intercepting the - (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType method.
In that method I had a block of code which looked like this:
NSMutableURLRequest *newRequest = [request mutableCopy];
for(NSString *key in [customHeaders allKeys]) {
[newRequest setValue:[customHeaders valueForKey:key] forHTTPHeaderField:key];
}
[self loadRequest:newRequest];
But for some unknown reason it was causing the web view to not load anything (blank frame) and the error message NSURLErrorCancelled (-999) comes up (all known fixes don't fix it for me).
So I am at a loss as to what to do. How can I send a custom header along with a UIWebView request?
Many thanks!
